I made a mistake. I chose Mac instead of PC. I went back to correct my mistake, but the ESET site says the validation code is already registered (what ever that means). No way to correct the mistake. Background: At work, an ESET representative gave out free gold aluminum ESET 1 yr protection cards, with a validation code on the back. Expected Result: Validation Code is registered upon the validation of the installation, and/or when ESET is successfully installed. I need the PC version. What do I do, other than vent here? (sighs)
